2013-07-15Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
2012-09-25disk: get_device_and_partition() "auto" partition and cleanupStephen Warren
Rework get_device_and_partition() to: a) Implement a new partition ID of "auto", which requests that U-Boot search for the first "bootable" partition, and fall back to the first valid partition if none is found. This way, users don't need to specify an explicit partition in their commands. b) Make use of get_device(). c) Add parameter to indicate whether returning a whole device is acceptable, or whether a partition is mandatory. d) Make error-checking of the user's device-/partition-specification more complete. In particular, if strtoul() doesn't convert all characters, it's an error rather than just ignored. The resultant device/partition returned by the function will be as follows, based on whether the disk has a partition table (ptable) or not, and whether the calling command allows the whole device to be returned or not. (D and P are integers, P >= 1) D D: No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: device D partition 1 D:0 !allow_whole_dev: error allow_whole_dev: device D D:P No ptable: error ptable: device D partition P D:auto No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: first partition in device D with bootable flag set. If none, first valid paratition in device D. Note: In order to review this patch, it's probably easiest to simply look at the file contents post-application, rather than reading the patch itself. Signed-off-by: Rob Herring <rob.herring@calxeda.com> [swarren: Rob implemented scanning for bootable partitions. I fixed a couple of issues there, switched the syntax to ":auto", added the error-checking rework, and ":0" syntax for the whole device] Signed-off-by: Stephen Warren <swarren@nvidia.com>

2012-09-25combine block device load commands into common functionRob Herring
All the raw block load commands duplicate the same code. Starting with the ide version as it has progress updates convert ide, usb, and scsi boot commands to all use a common version. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
